JOSEPH EMENAKER, OF HAMILTON, OHIO, ASSIGNOR OF ONE-THIRD TO GEORGE MITCHELL AND ONE-THIRD TO MIKE F. FRITTERER, OF HAMILTON, OHIO.

WINDOW.

To all whom it may concern:

Be it known that I, JOSEPH EMENAKER, citizen of the United States, residing at Hamilton, in the county of Butler and State of Ohio, have invented certain new and useful Improvements in Window-Sashes, of which the following is a specification.

This invention relates to window sashes and means for balancing the same and it has for one of its objects to provide a sash embodying side sections and a glass-carrying section detachably connected to the side sections, whereby it may be readily removed to facilitate cleaning of the glass and may be as readily replaced and secured to the side sec tions so as to move therewith.

Another object of the invention is the provision of a sash comprising side sections, a glass-carrying section arranged between and detachably connected to the side sections, and weather excluding and anti rattling packing carried by the side sections and interposed between the same and the glass-carrying section.

Another object is the provision of simple and durable means cooperating with the side sections of the sash and adapted to efficiently balance the sash so as to permit of the same being moved up and down with the expenditure of but a minimum amount of effort.

To the attainment of the foregoing objects, the invention consists in the peculiar construction, novel combinations and adaptation of parts hereinafter described and particularly pointed out in the claims appended.

In the accompanying drawings which are made a part hereof: Figure 1 is a front elevation of a sash frame and sashes constructed in accordance with my invention. Fig. 2 is a detail view, partly in elevation and partly in vertical section, of my improvements. Fig. 3 is an enlarged detail, horizontal section taken in a plane above the meeting rails of the sashes, looking downward. Fig. 4 is a broken perspective view of one side section of one sash, removed. Fig. 5 is a broken perspective view of the portion of the glass-carrying section which cooperates with the said side section. Fig. 6 is a perspective view of one of the rack plates, removed. Fig. 7 is a vertical section of the same.

responding parts in all of the views of the drawings, referring to which:

A is a sash frame constructed according to my invention. The said frame is peculiar in that each of its side stiles a has parallel, vertical guide ways I), of dovetail form in crosssection, on its wall 0 adjacent to the sash, and vertically elongated openings (1 in said wall, and also has vertical guide ways 6 back of the wall 0 for a purpose resently set forth.

B B are vertically mova le weight bars arranged in the guide ways 6 of the frame stiles and having racks f on their sides adjacent to the stile walls 0.

O O are toothed wheels or spur gears mounted in the openings d of the stile walls a and intermeshed with the racks f of the weight bars B, and D D are the side sections of the sash, which side sections are of dovetail form in cross section to snugly occupy the guide ways I) on the stile walls 0 and are movable vertically in said guide ways. The said side sections D of the sash are provided on their sides adjacent to the stile walls 0 with rack plates E, and these rack plates are intermeshed with the toothed wheels or spur gears O, whereby it will be seen that the weight bars B balance the sash so that the latter may be moved up and down in the frame with the expenditure of but very little effort. In this connection it will be noticed that when either sash is raised its complementary weight bars B are moved downwardly, and when the sash is lowered its weight bars are raised, and this will be appreciated as an important advantage since it assures proper balancing of the sashes without the employment of the usual pulleys, cordsand weights generally resorted to for the purpose.

In their inner sides the side sections D of the sashes are provided with vertical grooves m, and in these grooves are arranged and suitably secured packing strips F, preferably rubber tubes as shown, which have for their office to obviate rattling and to pre vent the passage of air between the side sections D and the removable glass-carrying sections presently described of the sash. Each rack plate E is formed of a thin body slotted to form the rack teeth and secured, one to the outer edge of each section D.

Said plates are each provided with an integral pin G at its lower end and an upper enlarged portion extending over and forming a continuation of the upper end of the section D to which it is secured, said enlargement carrying a pivoted fastening member H. The pins G extend inwardly through their respective sections D and packing strips F, the fastening member H being hinged to the upper end of the section so as to swing vertically, and being provided with a depending projection'n, a slot p, and a finger por tion 7".

I I are the glass-carrying sections of the sashes. These sections I are rectangular in. form and are provided in the outer sides of their vertical bars with shallow grooves 8 de signed to receive the packing strips F on the side sections D. The said sections I are also provided in their lower corners with notches J designed to receive the pins G on the side sections D, and at their upper corners they are equipped with angle plates K, slotted at L to receive the projections a of the fastening members H, and bearing turn-buttons M which are designed to pass through the slots .1) of said fastening members I-I and be turned into engagement therewith.

From the foregoing it will be apparent that when the pins G on the side sections D are arranged in the notches J of the glass carrying sections I, and the fastening members H of the side sections D are swung down against and fastened to the glass-carrying sections I, each glass-carrying section will be fixed to its complementary pair of side sections so as to move up and down with said side sections as one piece. It will also be apparent that when the fastening members H are released from the glass-carryingsections and are swung upward on their respective hinge-pintles into a vertical position, the

glass-carrying sections can be swung on the.

pins G into a horizontal or approximately horizontal position, this in order that the outer sides of the glass may be thoroughly cleaned with easeand despatch. It will also be understood that when released from the fastening members H, the glass-carrying sections I of the sash may be quickly and easily removed entirely from the side sections D, as is desirable in case of fire or the like.

To replace and fasten the glass-carrying sections I of the sash in their respective side sections D, it is simply necessary to arrange the notches J of sections I on the pins G and swingsaid sections I upwardly to positions between and in vertical alinement with their respective side sections D, and then swing the fastening members H down into engagement with the glass-carrying sections and connect said members H to the glass-carrying sections through the medium of the turnbuttons M. In thus replacing the glasscarrying sections I, that of the upper-sash is first replaced, and then that of the lower sash. At this point it will be noted that in removing the glass-carrying sectionsI the order mentioned is reversedi. 6., the section I of the lower sash is removed before the section I .of the upper sash. From this latter it follows that when both sashes are lowered, the section I of the lower sash may be swung down and into an apartment from between its respective side sections D, and then the section I of the upper sash may be swung down and into the apartment from between its respective side sections, and laid upon the first mentioned section I.

It will be gathered from the foregoing that in addition to the practical advantages ascribed to my novel sash frame and sashes, the same are simple, compact and inexpensive in construction, and are well adapted to withstand the usage to which such devices are ordinarily subjected.

The construction shown and described in detail constitutes the present and preferred embodiment of my invention, but it is obvious that in practice such changes or modifications may be made as fairly fall within the scope of my invention as claimed.

Having described my invention, what I claim and desire to secure by Letters Patent, is:
